How to make the AltTabPreview smaller on Windows 11?

Windows 11 introduces a new feature called AltTabPreview, which allows you to quickly switch between open applications. When you press the Alt and Tab keys together, a preview of all open windows appears on the screen. However, some users may find the default size of the AltTabPreview window too large and want to make it smaller. In this article, we will guide you through the process of making the AltTabPreview smaller on Windows 11.

Method 1: Using the Settings App

The easiest way to change the size of the AltTabPreview window is through the Windows Settings app. Follow these steps:

1. Open the Settings app by clicking on the Start button and selecting the gear icon.
2. In the Settings window, click on the "System" category.
3. On the left sidebar, click on "Multitasking".
4. Scroll down to the "Alt + Tab" section.
5. Under "Pressing Alt + Tab shows", select the "Open windows and all tabs in Edge" option.
6. Below that, you will find the "Adjust the size of text, apps, and other items" slider. Move the slider to the left to make the AltTabPreview window smaller or to the right to make it larger.
7. As you move the slider, you will see a preview of the new AltTabPreview size. Adjust it until you are satisfied with the size.
8. Close the Settings app.

Now, when you press Alt and Tab together, the AltTabPreview window will appear in the size you have set.

Method 2: Using the Registry Editor

If you prefer to make advanced changes to the Windows registry, you can use the Registry Editor to adjust the size of the AltTabPreview window. Here's how:

1. Press the Windows key + R to open the Run dialog box.
2. Type "regedit" (without quotes) and press Enter. This will open the Registry Editor.
3. In the Registry Editor, navigate to the following path:

4. Right-click on an empty space in the right pane and select "New" > "DWORD (32-bit) Value".
5. Name the new value "Grid_backgroundPercent" (without quotes).
6. Double-click on the newly created value and set its "Value data" to a number between 0 and 100. This number represents the percentage of the screen width that the AltTabPreview window will occupy. For example, if you set it to 50, the window will take up half the screen width.
7. Click OK to save the changes.
8. Close the Registry Editor.

After making these changes, the AltTabPreview window will appear in the size you specified.

Customizing the size of the AltTabPreview window on Windows 11 can help improve your multitasking experience. Whether you prefer a smaller or larger window, you can easily adjust it using either the Settings app or the Registry Editor. Experiment with different sizes until you find the one that suits your needs best.
